Question 1
The effects of carcinoid syndrome are related to the release of: (Select 2)
A. Choline acetyltransferase
B. Histamine
C. Parathyroid Hormone
D. Serotonin
CORRECT ANSWER
B. Histamine
D. Serotonin
Carcinoid tumors are most often in the gastrointestinal tract. Carcinoid tumors produce
carcinoid syndrome if the tumor's secretory substances do not first drain into the hepatic
system.
The unmetabolized secretions include serotonin, histamine, kinins, prostaglandins E and F,
and Substance P.
Diarrhea, cutaneous flushing, bronchoconstriction, hypotension, abdominal pain,
hepatomegaly, and heart disease can be symptoms.
Question 2
Which preanesthesia checkout recommendations on the anesthesia gas machine should
be repeated before each case? (Select 2)
1
,A. Calibrate the oxygen sensor and check the low-oxygen alarm
B. Conduct a breathing system pressure and leak test
C. Perform a low-pressure leak test
D. Verify patient suction is adequate to clear the airway
CORRECT ANSWER
B. Conduct a breathing system pressure and leak test
D. Verify patient suction is adequate to clear the airway
The FDA checkout recommends that a leak test is provided with the change of an anesthetic
circuit to assure that it is patent, free of leaks, and withstands continuous pressure. Verify
that suction is adequate to clear the patient's airway.
Question 3
An interincisor distance of how many centimeters is suggested to indicate a difficult
intubation?
A. 3
B. 5
C. 7
D. 9
CORRECT ANSWER
A. 3 cm
An interincisor distance less than 3 cm (2 fingerbreadths), measured from the upper to the
lower incisors with maximal mouth opening, can suggest possible difficult intubation. Some
studies have used 4 or 4.5 cm as the cutoff.

,Question 4
Which drugs are dose based on total body weight in the patient with a BMI of 39 kg/m²?
(Select 2)
A. Cisatracurium (Nimbex)
B. Lidocaine (Xylocaine)
C. Propofol (Diprivan)
D. Remifentanil (Ultiva)
CORRECT ANSWER
A. Cisatracurium (Nimbex)
B. Lidocaine (Xylocaine)
The increased fat content of obese patients affects the volume of distribution of drugs.
Cisatracurium and lidocaine are dosed based on total body weight.
Propofol and remifentanil are dosed based on lean body weight.
Question 5
Which is the major mineralcorticoid produced in the adrenal cortex?
A. Aldosterone
B. Androgen
C. Cortisol
D. Epinephrine
CORRECT ANSWER
A. Aldosterone
3
, Aldosterone is the principal mineralcorticoid secreted by the adrenal cortex. It is involved in
volume regulation within the body. Its effects on the kidney allows for sodium reabsorption
in exchange for potassium or hydrogen ion excretion. The two major control mechanisms for
aldosterone release are angiotensin II and serum potassium level. An understanding of
aldosterone is necessary in relation to fluid management of patients and also in the impact it
has on the kidneys.
Question 6
Which gives the MOST rapid detection of an accidental extubation?
A. Blood pressure monitoring
B. Capnography
C. Electrocardiography
D. Pulse oximetry
CORRECT ANSWER
B. Capnography
Extubation is more rapidly detected by monitoring ETCO2 than with pulse oximetry and
other vital sign monitoring, as one would see a reading of little to no expired ETCO2 first.
Question 7
Damage to which nerve would cause vocal cord paralysis?
A. Glossopharyngeal
B. Hypoglossal
C. Recurrent laryngeal
4
